"It's not just simply adding objects to pre-defined chassis to create the desired effect, although the game does have some pre-built ones for you to add on to if you like. Every block can be placed individually including all the superstructure, and then the game's physics goes to work and, voila, a vehicle.
But the screenshots are only going to tell part of the story. This is a complete Lego experience, and you can keep on clicking those blocks together. During the demo, a towering statue of Mario, which one of the testers made, was shown off -- and you can apparently drive it, though we're just treated to seeing his head cheekily blown off to demonstrate how the vehicles are made of individual objects.
This is only the start. A tester tells me about that during an internal competition to see what was possible, he constructed a functioning space shuttle, complete with ejectable boosters. When they were sent spinning into the ether, a pair of wings slid into place, allowing you to fly the titan."
